Balkans Lurch from Killer Blizzards to Destructive Floods

ALEXA STANKOVIC/AFP/Getty Images(BELGRADE, Serbia) -- The Arctic cold is over for now, but that does not mean the Balkans are out of the woods yet. In fact, if the weather gets too warm too fast, the troubles may only be beginning.

Already hundreds of boats and barges have been crushed by cascading ice on the Danube River, and fears are growing that a thaw accompanied by spring rains will cause massive flooding and even landslides. The snow through much of the region is still five times its normal depth.

"We've got a situation that could be problematic," Aleksandar Prodanovic, flood control expert in Serbia told ABC News. "You have to take into consideration March and April rain as well as couple of weeks of winter left."

When a freeze gripped Europe in the end of January and first half of February, a thick layer of ice was formed on the Danube -- in some places as thich as 18 inches. Ship traffic was halted in many areas of Europe's busy waterways.

But now, with temperatures climbing, the ice has begun breaking up around the Serb capital of Belgrade, and damage has already been significant.

In Belgrade, huge ice chunks crashed into hundreds of anchored boats and swept away a number of barges. A couple of Belgrade's most popular floating restaurants have sunk. Now the U.N. is warning that parts of central and eastern Europe, until recently paralyzed by heavy snow, could face another catastrophe.

Margareta Wahlstroem, the U.N. secretary-general's special representative for disaster risk reduction, said in a statement in Geneva that there are warning signs that, "destructive floods will add to the loss of life and economic assets" as temperatures rise. In addition to the flood warnings, Serbian emergency officials warned of a risk of landslides in some 2,300 locations, where the heaviest snow has fallen in the lowlands.

In neighboring Bosnia, emergency crews are preparing for a fresh battle with winter when rivers overflow with snowmelt. Bosnians are also being warned of the danger of possible landslides and citizens are asked to contribute to the country's recovery by removing snow around their homes and trying to control of melting water.

Raging Waters In Australia and Brazil the Product of Global Warming, Say Scientists

Photo Courtesy - Getty Images(SAN DIEGO) -- The pictures Thursday from around the world of dramatic rooftop rescues from raging waters make it seem as though natural disasters are becoming an everyday occurrence. But they're not all that natural; climate scientists say man-made global warming is the sudden force behind the forces of nature.

In the mountains of southeast Brazil, more than 340 people have died after fierce mudslides swept away homes. At least 50 are still missing and victims continue to search for loved ones. On the other side of the globe, floods in Queensland, Australia have ravaged an area the size of France and Germany combined.

And in Sri Lanka, officials say flooding there has affected more than a million people, and the death toll has risen to 23. Sewage lines and holding tanks have overflowed in the floods, and a spokesperson for the health ministry there said officials are concerned about waterborne diseases like typhoid and diarrhea.

"If left unchecked, climate warming will continue so the things that we're having hints of now, foretastes of now, will come stronger," Richard Sommerville, a climate scientist at the University of California at San Diego and author of The Forgiving Air: Understanding Environmental Change, said.

The extreme weather the world has seen is part of a larger trend, he said. "The world is warming up....It's warming for sure and science is very confident that most of the warming is due to human causes."

Every time we burn fossil fuels like coal, oil and natural gas, Sommerville said, we emit carbon dioxide into the atmosphere. Now, climate scientists see "the changed odds, the loaded dice that favors more extreme events and more high temperature records being broken," he said.

The decade that just ended saw nine of the 10 warmest years on record, and warmer temperatures mean more moisture in the air. That moisture can fall as torrential, flooding rains in the summertime or blizzards in the winter.

"Because the whole water cycle speeds up in a warming world, there's more water in the atmosphere today than there was a few years ago on average, and you're seeing a lot of that in the heavy rains and floods for example in Australia," Sommervile said.
